Definitions

  • the present invention relates to hitherto unknown intermediates of the below formula I for use in the synthesis of prodrugs.
  • the said prodrug is non-toxic and, when administered to a warm-blooded animal including a human being, is enzymatically and/or chemically cleaved in such a manner as to release the drug at its target or site of activity, quantitatively and at a desirable rate, while the remaining cleaved moiety remains non-toxic and is metabolized in such a manner that non-toxic metabolic products are produced.
  • the prodrug can be provided without excessive costs in connection with its production, in particular without an appreciable loss of drug itself during its production and recovery, since the drug is usually the more expensive part of the prodrug.
  • the intermediate used to react with the drug in providing the prodrug should advantageously be stable and still be reasonably reactive.
  • acyloxyalkoxycarbonyl derivatives have become interesting bioreversible prodrug moieties of drugs and medicaments which are more readily bioavailable than the drug itself, and further are less irritating to topical and gastric mucosal membranes and are more permeable through such membranes.
  • R 1 may be further substituted, and its chain be interrupted by hetero atoms like oxygen, or by carbonyl group(s).
  • R 3 means hydrogen or C 1 -C 3 alkyl. Esters of this type have for instance been used as prodrugs of R'COOH and have been shown to be enzymatically hydrolyzed in man. Obviously such esters will also liberate D-H.
  • esters of the formula II have been produced in a multi-step procedure, confer J. Med. Chem. 1988, 31, p. 318ff, where the drug (containing a primary or secondary amine group being the point of reaction) is reacted with a compound of formula III in which formula, R 1' and R are hydrogen or lower alkyl.
  • the relationship between the reactivities of the two electrophilic centres in (3) is temporarily reversed by conversion of the acid chloride function to the less reactive carbonothioate group of (4).
  • the acid chloride function of (7) (being the desired intermediate of formula I) is finally restored by chlorination.
  • the double esters (6) were mostly prepared by stirring a suspension of sodium carboxylate in dimethylformamide with the iodo compound (5) at room temperature for 20 hours.
  • Simple carboxylic acids tend to give higher yields (80-100%) than carboxylic acids containing additional functional groups.
  • Other methods are workable, confer e.g. Scheme A, methods E, F, and J (Examples 9, 10, and 14, respectively).
  • the double esters (6) were generally pure enough for subsequent conversion, in step 4 of Scheme A, to the desired intermediates (7) by restoring the acid chloride function through reaction with sulfuryl chloride, preferably in the presence of a catalytic amount of boron trifluoride etherate at -25 - -30 ° C and subsequent stirring at 0 ° C for one hour and half an hour at room temperature.
  • the distillable compounds (7) were produced in high yields and could be kept without deterioration for years in a refrigerator.
  • the synthetic sequence is not restricted to acyloxymethyl carbonochloridates.
  • 1-chloroalkyl carbonochloridates for (3) and treating the derived 0-1-chloroalkyl S-alkyl carbonothioate with TBA butanoate in tetrahydrofuran for a suitable period of time, followed by sulfuryl chloride treatment provided a solution of 1-butanoyloxyalkyl carbonochloridate, but these intermediates seem to be less stable than (7).
  • the present intermediates of formula I can generally be prepared by reacting a 1-haloalkyl carbonochloridate of the formula IV where R 3 has the above meanings, is reacted with R 2 SR 4 , R 2 being C 1 -C 4 alkyl, and R 4 being hydrogen or an alkali metal ion, to form a 1-haloalkyl carbonothioate of the formula V R 2 and R 3 having the above meanings, which is transformed into a 1-acyloxyalkyl carbonothioate of the formula VI R 1 , R 2 , and R 3 having the above meanings, by reaction with a salt of a carboxylic acid R 1 COOH, R 1 having the above meanings, and finally reacting the compound of formula VI with a chlorinating agent to yield the desired intermediate of formula I.
  • R 3 H
  • the present intermediates are preferably being prepared by converting the compound of formula V to the corresponding iodide by reaction with sodium iodide, before transforming it via VI to I.
  • the preferred chlorinating agent used in the final step of the preparation of the present intermediates is sulfuryl chloride.
  • the present intermediates of the formula I can be provided in good yields and of reasonable costs, that they are stable, and even very reactive, in their intended use in the production of prodrugs. Due to the polyfunctionality of the intermediates, and the known catalytic decomposition of simple alkyl carbonochloridates, acylation reactions like the one used in providing the desired prodrugs could be expected to be troublesome, but this turned out not to be so, as illustrated by the non-optimized reactions of I with a few hydroxyl or amino group containing compounds (Examples 16-21).
  • the present intermediates are effective means in the production of the prodrugs in question, and they provide said final prodrugs in good yields in one step processes.
  • Example 3 The Procedure of Example 3 is slightly modified by increasing the amount of Nal to 30 g (200 ml), adding NaHCO 3 (0.8 g, 10 mmol), and heating at 40 °C for 4 h. Yield: 23.1 g (94%).
